我有这个代码:
def edit
@ship = Ship.find(params[:id])
authorize! if can? :create, @ship
#authorize! if can? :update, @ship
#unauthorized! if cannot? :update, @ship
end
我收到了这个错误:
ArgumentError at /ships/4/edit
wrong number of arguments (0 for 2+)
这突出了这一行:
authorize! if can? :create, @ship
我已经尝试了很多东西,但也尝试了我们以前的东西,那就是:
authorize! @ship
并且没有用角色重写用户系统,我不知道如何解决这个问题。
这是我的能力课:
class Ability
include CanCan::Ability
def initialize(user)
#if !user
if user.try(:admin?)
can :manage, :all
return
elsif !user
can :read, Ship
can :read, Planet
return
else
can :read, :all
#can :manage, Ship, :user_id => user.id
can :manage, Ship do |ship|
ship.try(:user) == user
end
end
end
